SAFE.

SPECIFICATION forming part of Letters Patent No. 406,122, dated July 2, 1889.

Application filed October 31, 1888.

To aZZ whom it may concern: Be it known that I, JOHN J. BROWN, of WVest Oovington, in the county of Kenton and State of Kentucky, have-invented a new and useful Improvement in Fire-Proof andBurg lar-Proof Safes, which improvement is fully set forth in the following specification and accompanying drawings. I

Figure I is a perspective view of my improved safe-frame; Fig. II, a perspective view of the safe-door frame; Fig. III, enlarged sectional view of one corner of the safe frame and door, showing the manner of constructing the interlocking flutes; and Figs. IV and V, sectional views of the old-style frames.

This invention relates to safes; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Fig. I represents a safe-frame cast entire in one piece. The limbs A B O of the safe are .preferably formed in the shape of curved angle-bars in cross-section, as shown, and the front portion of the safe or the door-jamb has fluted faces, as will be hereinafter more particularly pointed out, the whole being castv together in one piece. It is obvious that a skeleton or frame so constructed is not as liable to be sprung or bulged in a fire as if made in the ordinary way and riveted together. The door-frame D is in like manner cast in one piece, with fluted faces to correspond with the fluted faces of the body of the safe.

In order to illustrate the interlocking flutes of the door and frame and the advantages over the ordinary structure of safes, I show in Figs. IV and V cross-sections of the meeting faces of the frame and door. Thus E represents the safe-frame and F the door-frame. As ordinarily constructed, the meeting faces are formed in stepsor corrugated. The only portions of the steps or corrugations of the adjacent door and frame which are in contact: with each other are the outer step G of the frame and limb H of the door. All the other steps are slightly separated, as shown in Fig. IV. When, therefore, the safe has been ex: posed to fire, and the sides and top of the frame bulge out, the meeting faces G H separate, as shown in Fig. V, and a corrugated Serial No. 289,681. (No model.)

channel or way is formed between the meeting faces, through which the heat enters, thus destroying the contents of the safe. In order to obviate this, the j amb I of the safe-frame is provided with flutes, the outer faces J of which are approximately on a line with the side K of the safe, and the grooves L of the flutes are deep, so as to present high ridges M. The door-frame N has similarly-constructed flutes, with contours corresponding to the general outlines of the frame-flutes, but not in contact therewith, as shownin Fig. III. The outer faces 0 P of the frame and door are, however, in contact, the same as in the case of the ordinary safes. (Shown at G H, Fig. IV.) It will thus be seen that while the inclinations of the flutes in the safe and doorframes are so arranged relatively with each other that the hooked flutes will not interfere with each other when the door is opened or closed, the moment there is an outward or bulging movement of the frame K the short faces of the flutes come in contact with each other and close up the channel between the door and frame. WVhile in the case of the step or corrugated safes the bulging movement causes the separation or parting of the contact-faces G H, the other steps or corrugations are caused to still farther separate. In myinvention, however, the moment the meeting faces 0 P separate the fluted portions interlock or come in contact, thus forming a tight joint, preventing danger to the contents of the safe, as well as acting in the capacity of a support for the frame.

WVhat I claim as new is 1. A safe having a fluted jamb cast integral with the entire safe-skeleton, substantially as herein set forth.

2. A safe havinga fluted jamb cast integral with the entire safe-skeleton, in combination with a door-frame having fluted meeting faces, substantially as herein set forth.

A safe having a fluted jamb cast integral with the entire safe-skeleton, in combination I with a door frame or skeleton having fluted meeting faces cast integral with the doorframe, substantially as herein set forth.
